The idea with this program is that you have pools of tracks in the form of Spotify playlists. This program will make a track list based on the supplied playlists. The list of tracks will be randomly chosen.
java -jar spotify-playlist-pools-assembly-1.0-SNAPSHOT.jar -a <artist-frequency> <playlists>To authorize against the Spotify webapi the program also uses client credentials to authorize against the Spotify webapi. There are tree ways to authorize
against Spotify, described here. With the Client credintials flow you login through the clientId and
clientSecret found in the developer site for your application. To run the program you need to add the
clientId and clientSectret separated by colon (<clientId>:<clientSecret>) in a file called secret.txt.
